Bone filled in

[Martin Wyness]

 

 

Hi all,

My first attempt at creating a bone print of dog radius ulna using the fantastic Embodi3D procedure .  

I see there is too much filling in of space between between and around antebrachial bones  -  this is not evident on the original CT.  Can I tweak settings to better isolate radius and ulna ?  I see beautifully isolated examples on this site and feel I am missing a trick here!  

One point - our CT is cone beam - does that make any difference to stl creation ?

Any advice much appreciated.

Try adjusting the threshold on our democratiz3D app.

 Thanks, Guru. 

I managed to make threshold adjustment in Slicer and then tidy a bit in meshmixer.  Will apply same threshold setting here next time and see if it works. 

Cheers,

If you increase the threshold value (150->250 Hounsfield units), that will tend to include less bone in the model. If decrease it, more bone will be included. 

 

Just want to check -- are you starting with a CT or an MRI. CTs work better.

 

Hope this helps.

Hi Mike - starting with Cone beam CT files.  Will play with Hounsfield settings next time. 

For this particular case I learned enough on Slicer and Meshmixer to get the job done.
